When the USB device is connected, FreeBSD creates not one, but three
device nodes in /dev, e.g.: /dev/ttyU0, /dev/ttyU0.init, and
/dev/ttyU0.lock.
As a result, this leads to the USB variable containing 3 paths
(and therefore, whitespace) and messages like this one:
Device /dev/ttyU0
/dev/ttyU0.init
/dev/ttyU0.lock has appeared; assuming it is the controller.
This changes fixes the use of the -z flag of "[" (see test(1)). Also, it
removes undesired paths from the USB variable, leaving only
one path there (i.e., "/dev/ttyU0").
* Fix how USB queue overflow is handled in chibios.
This commit reverts PR 12472 (commit c823fe2d3f23ed090e36ce39beed4c448298bd2f),
and it implements the original intent of the commit in a better way.
The original intent of the above mentioned commit was to not deadlock the
keyboard when console is enabled, and hid_listen is not started.
The above mentioned commit had a few drawbacks:
1) When a lot of data was printed to the console, the queue would get full,
and drop data, even if hid_listen was running. (For example having matrix debug
enabled just didn't work right at all)
2) I believe the function in which this was implemented is used by all other
USB endpoints, so with the above change, overflow, and data loss could
happen in other important functions of QMK as well.
This commit implements deadlock prevention in a slightly similar way to how
it's done on AVR. There is an additional static local variable, that memorizes
whether the console has timeouted before. If we are in the timeouted=false
state, then we send the character normally with a 5ms timeout. If it does
time out, then hid_listen is likely not running, and future characters should
not be sent with a timeout, but those characters should still be sent if there
is space in the queue. The difference between the AVR implementation and this
one is that the AVR implementation checks the queue state directly, but this
implementation instead attempts to write the character with a zero timeout.
If it fails, then we remain in the timeouted=true state, if it succeeds, then
hid_listen started removing data from the queue, so we can go out of the
timeouted=true state.
* Added comment explaining the timeouted logic to console flow control.
* Console flow control: refactor chibios flowcontrol code to make it more readable, and rename the timeouted variable to timed_out on both chibios and lufa. Changed comments to says timed_out is an approximation of listener_disconnected, to make it clear that it's not the same thing
* fix typo
Before this commit, attaching an ARM-based (i.e. ChibiOS-based) keyboard that
uses CONSOLE_ENABLE = yes and produces debug messages would deadlock the
keyboard unless one was running hid_listen.
With this commit, dead-locking writes to the queue are detected and prevented.

* Fix keycode mappings for via and ensure they don't change within protocol
* Update keycodes
* Fix broken keyboards
* added the missing keycodes found in via
* Remove invalid keycodes

* Modified tmk_core/rules.mk to avoid linking errors
Added -fcommon flag to avoid linking errors due to multiple variable definitions. Though this is neither a definitive nor good solution, proper changes and use of extern keyword to avoid those multiple definitions must be made
* Comment updated
* Initial refactor of ARM SLEEP_LED to enable more platforms
* fix build issues
* Disable SLEEP_LED for boards with no caps lock code
* Enable GPT14 for boards with caps lock code and SLEEP_LED enabled
* Enable GPT for boards with caps lock code and SLEEP_LED enabled
* tmk_core/common/report.h: define `enum mouse_buttons` in terms of `#define MOUSE_BTN_MASK()`
* tmk_core/common/action.c: collapse multiple `case KC_MS_BTN[1-8]:` into single `MOUSE_BTN_MASK(action.key.code - KC_MS_BTN1)`
We all love tapping on our keyboards but this is taking the piss.
This saves ~134 bytes on my ATmega32.

* resolve race condition between suspend and wake in LUFA
* avoid multiple calls to suspend_power_down() / suspend_wakeup_init()
* Remove duplicate suspend_power_down_kb() call
* pause on wakeup to wait for USB state to settle
* need the repeated suspend_power_down() (that's where the sleep is)
* more efficient implementation
* fine tune the pause after sending wakeup
* speculative chibios version of pause-after-wake
* make wakeup delay configurable, and adjust value
* better location for wakeup delay
* Add support for 8 buttons to mouse report
This includes support for 8 buttons in mousekeys. However, this does move the keys around due to the fact that the last mousekey keycode is already 0xFF, so any past that would not work with register_code and the like, breaking them for tap hold keys, encoders, and other features.
* Update mouse key docs
* Add changes based on feedback
* Fix VUSB report size comment

* Allow recording of the last matrix activity time, to simplify implementation of display timeouts and the like.
* Add requested changes from code review.
* Simplify split matrix last changed.
* Add proper prototypes for Tap-Hold Per Key functions
* Fix handwired/tennie default keymap
* Remove unneeded references
* Fix tapping term per key check in space cadet
* Pre-emptive fix for tap dance
* Fix marksard/leftover30
* Replace hard coded tapping term with define
* Add target 'build-for-compare' to `build_keyboard.mk`
The `build-for-compare` target provides an easy way to check the md5 checksum of the generated binary.
You can easily see if there is any change in the generated binaries between the two versions, as in the example below.
